... to elucidate the effect of Rayleigh number (10 4 –10 6 ), Prandtl number (10–100), Bingham number (0.01 to Bn max ), and the gap between the two cylinders in terms of the geometric parameters (0 to −0.25 for vertical alignment and 0.15 to 0.35 for diagonal alignment) on the detailed structure of the flow field...

... walls. The current study covers the range of Rayleigh number (10 3 ≤ Ra ≤ 10 6 ) and a fixed Prandtl number of 0.71 for all cases. The effect of size of obstacle is studied in detail for single obstacle. It is found that the average heat transfer along the hot wall increases with the increase in size...

..., was provided at various solid volume fractions. The study is carried out numerically for a range of Rayleigh numbers, solid volume fractions, partition heights, and aspect ratios. Regions with the same velocity and temperature distributions are identified as a symmetry of sections. One-half...
